"Tom was not diagnosed with a concussion last year," agent Don Yee said in a statement to ESPN, NFL Network and other media outlets. "Many of the protocols and safeguards still are evolving, and it's obviously a good thing the organization and everyone close to him is vigilant and always looking out for his health."
The statement came two days after Brady's wife, Gisele Bundchen, appeared on "CBS This Morning" and said her husband "had a concussion last year" and alluded to more concussions during his career.
The supermodel was asked by CBS' Charlie Rose of her thoughts on Brady's plans to play into his mid-40s and whether she wants him to retire from football.
"I just have to say, as a wife, as you know (the NFL) is not the most, let's say, unaggressive sport. Football, he had a concussion last year," she said in the interview. "He has concussions pretty much every -- I mean we don't talk about it.
"But he has concussions and I don't really think it's a healthy thing for your body to go through. You know, that kind of aggression all the time, that cannot be healthy for you. I'm planning on having him be healthy and do a lot of fun things when we're like 100 I hope."
--Brady signed a multiyear endorsement deal with British luxury car manufacturer Aston Martin to pitch a model that starts at $211,995.
The 104-year-old handmade car company announced that Brady will be driving and pitching the DB11 model.
"I'm no James Bond but ... Proud to announce my new partnership with (Aston Martin)!" Brady wrote on his Instagram page to confirm the deal, posting photos of himself with the car.
In addition, Aston Martin said Brady will "curate" his own version of the company's new Vanquish S -- a 580-horsepower coupe with a base price of more than $300,000. Only 12 of those cars will be made and sold to the public.
--Cleveland Browns defensive end Myles Garrett, the top overall pick of the 2017 draft, signed his four-year rookie contract.
The deal is worth an estimated $30.4 million with a $20.25 million signing bonus. The contract comes with a team option for the fifth season in 2021.
The Browns posted a video on Twitter of Garrett filling out the contract while Seal's "Kiss From A Rose" played in the background.
Garrett collected 141 tackles (47 for loss), 31 sacks and forced seven fumbles during his three-year career at Texas AM. The 6-foot-4 1/2, 272-pound Aggies standout was held to 8 1/2 sacks last season while he dealt with a high-ankle sprain.
--The Tampa Bay Buccaneers reached an agreement with free agent quarterback Ryan Fitzpatrick to serve as the backup to Jameis Winston.
The deal is for one year and worth a reported $3 million that includes incentives to take the base salary higher.
The 34-year-old Fitzpatrick has started 116 games over his 12 seasons in the NFL, including 27 the past two years with the New York Jets. He made $12 million last season.
--The Oakland Raiders took an important step toward having a Las Vegas stadium ready for the 2020 season when the Las Vegas Stadium Authority unanimously approved a conditional lease agreement for the team, multiple media outlets reported.
It was important to get the approval this week because Raiders president Marc Badain had said recently that appearing at the NFL owners meetings, which begin Monday in Chicago, without a lease could delay the team's move to Las Vegas by a year.
The next opportunity to present a lease would not be until the following owners meeting in October.
-- The Arizona Cardinals signed guard Dorian Johnson to a four-year rookie contract. Johnson was the team's fourth-round pick out of Pittsburgh in last month's NFL Draft.
Johnson was seen as a second-round pick who slid to the fourth because of a medical recheck that revealed a health condition related to his liver. It's producing enzymes at a rate five times higher than normal, but the 6-foot-5, 305-pound Johnson said he has had the condition his entire life and it is being controlled through medication.
Johnson started 40 consecutive games to finish his college career and became the first Panthers offensive lineman to earn first-team All-American honors since Ruben Brown in 1994.
-- The Indianapolis Colts signed outside linebacker Tarell Basham.
Basham, who was a third-round pick in last month's draft, recorded 158 tackles, a school-record 29.5 sacks and five forced fumbles during his 51-game career at Ohio University.
The 6-foot-4, 262-pounder was named the 2016 Mid-American Conference Defensive Player of the Year after leading the conference with 11.5 sacks last season.
